A late-winter cold blast was disrupting power and natural gas markets across the US, with temperatures forecast to reach record lows for the season. The grid operator covering the Dakotas to Louisiana warned of possible power-plant fuel restrictions, and Pacific Northwest power for Monday delivery hit its highest level in more than a decade.
Record heating demand and tight pipeline supply push gas and power prices higher during the cold spell. Higher energy costs can also raise the cost of gas-dependent processing and fertilizer inputs.
After 221 past bullish weather events, Natural Gas moved a median +3.3% over 5 sessions (61% higher; middle half -5.2% to +14.0%), and -0.3% over 20.
